We present spatially resolved analysis of a lensed galaxy, SDSS1958+5950 at z = 2.225, from the Cambridge Sloan Survey ofWide Arcs in the Sky. We use our new high-resolution imaging data to construct a robust lens model for the galaxy group at z = 0.214.We employ the updated lens model to combine the Integral Field Spectrographic observations on two highly distorted images of the lensed target. We adopt a forward-modelling approach to deconvolve the effects of point spread function from the...[Show more]
